It's not a correlation based on my method, tiko.
1. Watch for the amount of price change for the two companies.
2. When they are exactly equal
3. At the same time
That's what I call Price Change Parity. Very often, especially for CYDY, the correlated share price will immediately begin to function as either support or resistance. HGEN is more likely to take a few minutes to settle in, and will trade slightly above or below, but it will function as s/r in a little while.
Very often, within the last 2 hours of the session, share price will revert to the s/r level indicated with Price Change Parity, unless the company begins trending, as HGEN did yesterday.
It's an obvious algorithm. All I did was observe it.
D4 is not going to phase me in the least. But nobody else is, either. Nevertheless, I appreciate your encouragement.
